On the All-Star ballot, Brandon Moss is listed as a designated hitter.

On the A’s lineup card most days, Moss is listed as a first baseman.

So it’s easy to forget that Moss began his baseball life as an outfielder.

The Baltimore Orioles won’t soon forget, not after Friday night, when Moss threw a bullet from right field to the plate, enabling Derek Norris to tag out the sliding Nick Markakis, thereby denying the Orioles a 10th inning win.

The A’s went on to win the game 4-3 in the 11th, when Moss, as he does from time to time, struck out.

“I’m not a great outfielder as far as range and stuff,’’ Moss said. “But people don’t remember that I have a real good arm. That’s really my only defensive tool, but I’ve always had a real good arm. And when you don’t play the outfield a lot, and you play first base, people don’t remember.’’
